Letters Patent No. 98,419, dated December 28, 1869.

; IMPROVEMENT IN SHIP-PUMPS.

The Schedule efen-ed to in these Letters Patent and making part of thesame.

To all whom. it may concern:

Be it known that I, BENJAMIN K. Rooms, of J onesport, in the county ofWashington and State of Maine, have invented a new and valuableImprovement in Ships Pumps; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawings,making a part of this specification, and'to the letters and figures ofreference marked thereon.

Figure 1, of the drawings, is a representation of a vertical section ofm y invention.

Figure 2 is a side vertical section of the same.

My invention relates to means for pumping water from the hold ot'avessel; and

It consists mainly in the construction and novel arrangement of devicesintended to serve as efiicient means for the purpose designated.

The letter A, of the drawings, represents a ships hold, and letters B,two pump-cylinders arranged therein.

The letters 0 represent plunger-s, and letters D, the rods attachedthereto.

A cross-bar, E, unites the cylinders '13 at their tops, as shown.

The letter G represents a standard, with its hottom attached firmly tothe deck of the vessel, and

which passes upon and through the cross-bar E. Above this cross-bar, thestandard G is slotted, as shown, to provide for the attachment andmovements of the apparatus next mentioned.

The letter H represents a bent or curved lever, pivotcd within the slotof standard G, and having crossheads or handles a at each end, adaptedfor gangs of men, or by machinery, as the case may be.

The letter K represents a circular plate, attached to lever H, and theletter I 1, a circular ratchet, alfixed to said lever, of the formshown.

The letter N represents the walking-beam, pivoted in the slot ofstandard G, and to the ends of which, the rods D are hinged, as shown.

The letter P represents a circular ratchet, attached to the lower sideof walking-beam N, the teeth of which mesh and operate with the teeth ofratchet L, as shown on fig. 1.

The letter 0 represents a vertical lever, pivoted to the standard G, ai1.(l. having its bottom resting in a socket in the plateK." This leveris intended for use in conjunction with the lever H, or it may be usedfor pumping, attimes when the bars or handles of lever H are removed orbroken.

It will readily be perceived, that by the arrangement above described,immense power may be brought to bear upon the pumps at any moment, andthat such power is greatly economized by the leverage secured by theratehets, walking-beam, and lever-apparatus.

That portion of lever H that projects beyond the rods D is maderemovable, by means of the small pins 0, that hold such extended partsin place. This lastuamed arrangement is sometimes required, in orderthat the extended ends or handles of lever H may be taken out of the wayof the sailors or freight.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

A ships pump, having cylinders B, plungers O, rods D, standard G, leversH and a, plate K, ratchets L and P, and walking-beam N, constructed andarranged substantially as specified.

In testimony that I claim the above, I have hereunto subscribed my name,in the presence of two witnesses.
